Preheat oven to 350 degrees (F).
Separate dough into eight rectangles. Seal perforations.
Using a brush or spoon, spread melted butter all over crescent rolls. Sprinkle with cinnamon sugar mixture (2 tablespoons white sugar mixed with 1 teaspoon of cinnamon).
Roll up from long side; pinch edges to seal. Holding one end, loosely coil each.
Now you want to get in there with your fingers and spread out the dough some to make room for the filling. Just pull and stretch to make a nice dent in the middle.
Open can of apple pie filling and using a knife, cut apple slices into smaller chunks. Just keep poking and slicing around until all your apples are cut into more manageable pieces.
Place on cookie sheet that has been sprayed with nonstick spray. Top each coil with about 2-3 tablespoons of apple pie filling.
Sprinkle the tops with a bit more cinnamon sugar mixture.
Bake at 350(F) for 15-18 minutes, or until golden brown.
For the glaze, in a bowl, combine powdered sugar, vanilla and milk. Stir until smooth and drizzle over each warm danish. These taste best when served warm.
